Actually, I ment U-boot itself. When I said application, I was wrong. I ment for example command, which is part of U-Boot. If I want to exit when something is wrong within TFTP for example, I cannnot break execution and regain U-Boot shell? (Otherwise, I have to go back to calling functions in net.c, etc..., which is not what I want. I want to stop on the place error happened.)

Dear Drasko,

In message 5ec3d7930903130339t592e64a8o5ace302e06976ea@mail.gmail.com you wrote:

a application at any function when something goes wrong.

U-Boot itself has no exit, obviously.

But you mention "application", so I guess you are referring to stand- alone applications; these terminate when you return from the top level function. How you arrange for that is up to you. setjmp / long- jmp are usually trivial to implement / use.

Best regards,

Wolfgang Denk
